Current and Voltage Transformers 2. Electromagnetic voltage transformers 2.3 Secondary leads Voltage transformers are designed to maintain the specified accuracy in voltage output at their secondary terminals. To maintain this if long secondary leads are required, a distribution box can be fitted close to the VT to supply relay and metering
